" TOOL HOLDER FOR CULTIVATORS.

Application filed February 24, 1921.

To all whom it may concern: 1

Be it known that I, Cnannns H. /Vitirn, a citizen of the United States,residing at Moline, in the county of Rock Island and State of Illinois,have invented certain new and useful Improvements in Tool Holders forCultivators, of which the following is a specification, reference beinghad therein to the accompanying drawing.

My invention relates to tillage machines and more particularly to thatclass having earth stirring devices laterally adjustable to vary thedistance apart and vertically adjustable to vary their depth of work.

The object of my invention is to provide a simple and effective means ofadjustably securing earth stirring devices to machines of the classstated.

Referring to the drawings in which similar numerals indicate identicalparts-- ldigure 1 is a plan view of a cultivator embodying my invention.

Figure 2 is a side elevation of Figure 1.

Figure 3 is an enlarged detail plan view of my device as employed.

Figure 1 is a sectional view on the line fir-4c of Figure 3, and

Figure 5 is an enlarged perspective view of the tool holding clip.

I have shown my device as applied to a riding cultivator to the frontframe bar 1 of which are pivotally connected rearwardly extending dragbars 2, 3, 1 and 5, carrying at their rear extremities parallel bars 6and 7. The bars 6 and 7 are spaced apart one above the other, inparallel relation, and are bolted to castings 8 and 9 securedrespectively on the drag bars 2 and 5; the bar 6 is provided with aseries of equidistant notches 10 on each side which register withsimilar notches in the bar 7 and in which standards 11 and wedges 12 areadapted to be held by bifurcated holders 13. The latter are madepreferably of sheet metal bent upon itself to form a U, and are providedwith slots 14 and 15 in one arm which are in vertical alinementrespectively with slots 16 and 17 in the opposite arm.

The holders 13 are employed between the bars 6 and 7 and extend beyondthe latter on both sides so that the standards 11 and wedges 12 can bereadily inserted in the slots therein. in mounting a standard, to whichthe desired tool is supposed to be attached, the standard can be placedin the slots 14 Serial No. 447,382.

and 16 before the holder is passed between the bars 6 and'7, or theholder can be put in place between the bars 6 and 7 before the standardis inserted in the slots 1d and 16. After the standard is in place inthe slots 14 and 16 and engaged with notches in the bars 6 and 7, on theopposite sides of the latter I employ the wedge 12 in the slots 15 and17, the wedge engaging with notches in the bars 6 and 7 directlyopposite those in which the standard 11 rests, and by driving the wedgefirmly in place the parts are held rigidly together; the slot 17 is of alesser length than the slot 15 to conform to the slant of the wedge .12,and the width of the bars between opposite notches is greater than thespace 18 between the slots 14 and 15 and the slots 16 and 17 to providefor standards of varying sizes and to ensure rigidity in the relation ofthe assembled parts.

It will be readily understood that in providing numerous oppositenotches in the bars 6 and 7 the distance between the tools employed canbe increased or diminished as may be desired, and it is also evidentthat by reversing, or turning the holders end for end, the tools may becarried either to the front or rear of the bars 5 and 7.

What I claim is v 1. In a cultivator, the combination of a frame, barsmounted transversely thereon one above the other in parallel relation, aseries of notches in both edges of each bar, the notches in one barregistering with the notches in the other bar, each notch in one side ofeach bar being directly opposite a similar notch in the other sidethereof, a tool carrying standard, a holding means for the standardextending between the bars and beyond both sides thereof and adapted toreceive the standard on one side of the bars and to hold it in adjacentnotches, and means on the opposite side of the bars cooperating withsaid holding means and with adjacent notches to retain the standard inrigid contact with said bars.

2. In a cultivator, the combination of a frame, tool carrying barsmounted transversely thereon one above the other in parallel relation, atool standard, a bifurcated holder adapted to be inserted between saidbars and to extend beyond both sides thereof, slots in the arms of saidholder to receive said standard on one side of said bars,

slots in the arms of the holder on the opposite side of said bars toreceive a wedge in contact with said bars to hold the tool 4:. In acultivator, the combination of a frame, tool carrying bars mountedtransversely thereon one above the other in parallel relation, aseries'of notches in the sides of each bar, a bifurcated holderextending between the bars and beyond the sides thereof, slots in eachend of the arms of the holder extending respectively beyond the sides ofthe bars a tool standard held in the slots and adjacent notches on oneside of said bars, and a wedge. operating in the slots and adjacentnotches in the opposite side of the bars to place.
